patch "phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From d7119224bfe6e8efbf821a52db7da9530d790f07 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai <wens(a)csie.org> Date: Fri, 19 Jan 2018 17:25:41 +0800 Subject: phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving VBUS The AXP223 PMIC, like the AXP221, does not generate VBUS change interrupts when N_VBUSEN is used to drive VBUS for the OTG port on the board. This was not noticed until recently, as most A23/A33 boards use a GPIO pin that does not support interrupts for OTG ID detection. This forces the driver to use polling. However the A33-OlinuXino uses a pin that does support interrupts, so the driver uses them. However the VBUS interrupt never fires, and the driver never gets to update the VBUS status. This results in musb timing out waiting for VBUS to rise. This was worked around for the AXP221 by resorting to polling changes in commit 91d96f06a760 ("phy-sun4i-usb: Add workaround for missing Vbus det interrupts on A31"). This patch adds the A23 and A33 to the list of SoCs that need the workaround.

[PATCH] serial: mvebu-uart: fix tx lost characters

by Gabriel Matni

From: Gabriel Matni <gabriel.matni(a)exfo.com> Fixes missing characters on kernel console at low baud rates (i.e.9600). The driver should poll TX_RDY or TX_FIFO_EMP instead of TX_EMP to ensure that the transmitter holding register (THR) is ready to receive a new byte.

patch "phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From d7119224bfe6e8efbf821a52db7da9530d790f07 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai <wens(a)csie.org> Date: Fri, 19 Jan 2018 17:25:41 +0800 Subject: phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving VBUS The AXP223 PMIC, like the AXP221, does not generate VBUS change interrupts when N_VBUSEN is used to drive VBUS for the OTG port on the board. This was not noticed until recently, as most A23/A33 boards use a GPIO pin that does not support interrupts for OTG ID detection. This forces the driver to use polling. However the A33-OlinuXino uses a pin that does support interrupts, so the driver uses them. However the VBUS interrupt never fires, and the driver never gets to update the VBUS status. This results in musb timing out waiting for VBUS to rise. This was worked around for the AXP221 by resorting to polling changes in commit 91d96f06a760 ("phy-sun4i-usb: Add workaround for missing Vbus det interrupts on A31"). This patch adds the A23 and A33 to the list of SoCs that need the workaround.

[PATCH][v3] mtd: rawnand: fsl_ifc: Fix eccstat array overflow for IFC ver >= 2.0.0

by Jagdish Gediya

Number of ECC status registers i.e. (ECCSTATx) has been increased in IFC version 2.0.0 due to increase in SRAM size. This is causing eccstat array to over flow. So, replace eccstat array with u32 variable to make it fail-safe and independent of number of ECC status registers or SRAM size.

Applied "ASoC: ssm2602: Replace reg_default_raw with reg_default" to the asoc tree

by Mark Brown

The patch ASoC: ssm2602: Replace reg_default_raw with reg_default has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From a01df75ce737951ad13a08d101306e88c3f57cb2 Mon Sep 17 00:00:00 2001 From: James Kelly <jamespeterkelly(a)gmail.com> Date: Mon, 19 Mar 2018 21:29:50 +1100 Subject: [PATCH] ASoC: ssm2602: Replace reg_default_raw with reg_default SSM2602 driver is broken on recent kernels (at least since 4.9). User space applications such as amixer or alsamixer get EIO when attempting to access codec controls via the relevant IOCTLs. Root cause of these failures is the regcache_hw_init function in drivers/base/regmap/regcache.c, which prevents regmap cache initalization from the reg_defaults_raw element of the regmap_config structure when registers are write only. It also disables the regmap cache entirely when all registers are write only or volatile as is the case for the SSM2602 driver. Using the reg_defaults element of the regmap_config structure rather than the reg_defaults_raw element to initalize the regmap cache avoids the logic in the regcache_hw_init function entirely. It also makes this driver consistent with other ASoC codec drivers, as this driver was the ONLY codec driver that used the reg_defaults_raw element to initalize the cache. Tested on Digilent Zybo Z7 development board which has a SSM2603 codec chip connected to a Xilinx Zynq SoC.

[PATCH v3 1/5] tpm: fix intermittent failure with self tests

by Jarkko Sakkinen

From: James Bottomley <James.Bottomley(a)HansenPartnership.com> My Nuvoton 6xx in a Dell XPS-13 has been intermittently failing to work (necessitating a reboot). The problem seems to be that the TPM gets into a state where the partial self-test doesn't return TPM_RC_SUCCESS (meaning all tests have run to completion), but instead returns TPM_RC_TESTING (meaning some tests are still running in the background). There are various theories that resending the self-test command actually causes the tests to restart and thus triggers more TPM_RC_TESTING returns until the timeout is exceeded. There are several issues here: firstly being we shouldn't slow down the boot sequence waiting for the self test to complete once the TPM backgrounds them. It will actually make available all functions that have passed and if it gets a failure return TPM_RC_FAILURE to every subsequent command. So the fix is to kick off self tests once and if they return TPM_RC_TESTING log that as a backgrounded self test and continue on. In order to prevent other tpm users from seeing any TPM_RC_TESTING returns (which it might if they send a command that needs a TPM subsystem which is still under test), we loop in tpm_transmit_cmd until either a timeout or we don't get a TPM_RC_TESTING return. Finally, there have been observations of strange returns from a partial test. One Nuvoton is occasionally returning TPM_RC_COMMAND_CODE, so treat any unexpected return from a partial self test as an indication we need to run a full self test.

[PATCH v2] clk: mvebu: armada-38x: add support for missing clocks

by Richard Genoud

Clearfog boards can come with a CPU clocked at 1600MHz (commercial) or 1333MHz (industrial). They have also some dip-switches to select a different clock (666, 800, 1066, 1200). The funny thing is that the recovery button is on the MPP34 fq selector. So, when booting an industrial board with this button down, the frequency 666MHz is selected (and the kernel didn't boot). This patch add all the missing clocks. The only mode I didn't test is 2GHz (uboot found 4294MHz instead :/ ).

In all the driver _recv() functions, we need to use a u32 to unmarshal the response size, otherwise a bit flip of the 31st bit would cause the expected variable to go negative, which would then try to read a huge amount of data. Also sanity check that the expected amount of data is large enough for the TPM header.

[PATCH] tpm: fix potential buffer overruns caused by bit glitches on the bus

by Jarkko Sakkinen

From: Jeremy Boone <jeremy.boone(a)nccgroup.trust> commit c8e3e06d252155ad0e38a64a65ebb85638893025 upstream Discrete TPMs are often connected over slow serial buses which, on some platforms, can have glitches causing bit flips. If a bit does flip it could cause an overrun if it's in one of the size parameters, so sanity check that we're not overrunning the provided buffer when doing a memcpy().
