[PATCH v6] staging: greybus: introduce pwm_ops::apply

by Song Chen

Introduce newer .apply function in pwm_ops to replace legacy operations including enable, disable, config and set_polarity. This guarantees atomic changes of the pwm controller configuration. Signed-off-by: Song Chen <chensong_2000(a)189.cn> --- v2: 1, define duty_cycle and period as u64 in gb_pwm_config_operation. 2, define duty and period as u64 in gb_pwm_config_request. 3, disable before configuring duty and period if the eventual goal is a disabled state. v3: Regarding duty_cycle and period, I read more discussion in this thread, min, warn or -EINVAL, seems no perfect way acceptable for everyone. How about we limit their value to INT_MAX and throw a warning at the same time when they are wrong? v4: 1, explain why legacy operations are replaced. 2, cap the value of period and duty to U32_MAX. v5: 1, revise commit message. v6: 1, revise commit message. 2, explain why capping the value of period and duty to U32_MAX in comment. --- drivers/staging/greybus/pwm.c | 64 ++++++++++++++++++++++------------- 1 file changed, 40 insertions(+), 24 deletions(-) diff --git a/drivers/staging/greybus/pwm.c b/drivers/staging/greybus/pwm.c index 891a6a672378..ad20ec24031e 100644 --- a/drivers/staging/greybus/pwm.c +++ b/drivers/staging/greybus/pwm.c @@ -204,43 +204,59 @@ static void gb_pwm_free(struct pwm_chip *chip, struct pwm_device *pwm) gb_pwm_deactivate_operation(pwmc, pwm->hwpwm); } -static int gb_pwm_config(struct pwm_chip *chip, struct pwm_device *pwm, - int duty_ns, int period_ns) +static int gb_pwm_apply(struct pwm_chip *chip, struct pwm_device *pwm, + const struct pwm_state *state) { + int err; + bool enabled = pwm->state.enabled; + u64 period = state->period; + u64 duty_cycle = state->duty_cycle; struct gb_pwm_chip *pwmc = pwm_chip_to_gb_pwm_chip(chip); - return gb_pwm_config_operation(pwmc, pwm->hwpwm, duty_ns, period_ns); -}; + /* Set polarity */ + if (state->polarity != pwm->state.polarity) { + if (enabled) { + gb_pwm_disable_operation(pwmc, pwm->hwpwm); + enabled = false; + } + err = gb_pwm_set_polarity_operation(pwmc, pwm->hwpwm, state->polarity); + if (err) + return err; + } -static int gb_pwm_set_polarity(struct pwm_chip *chip, struct pwm_device *pwm, - enum pwm_polarity polarity) -{ - struct gb_pwm_chip *pwmc = pwm_chip_to_gb_pwm_chip(chip); + if (!state->enabled) { + if (enabled) + gb_pwm_disable_operation(pwmc, pwm->hwpwm); + return 0; + } - return gb_pwm_set_polarity_operation(pwmc, pwm->hwpwm, polarity); -}; + /* + * Set period and duty cycle + * + * PWM privodes 64-bit period and duty_cycle, but greybus only accepts + * 32-bit, so their values have to be limited to U32_MAX. + */ + if (period > U32_MAX) + period = U32_MAX; -static int gb_pwm_enable(struct pwm_chip *chip, struct pwm_device *pwm) -{ - struct gb_pwm_chip *pwmc = pwm_chip_to_gb_pwm_chip(chip); + if (duty_cycle > period) + duty_cycle = period; - return gb_pwm_enable_operation(pwmc, pwm->hwpwm); -}; + err = gb_pwm_config_operation(pwmc, pwm->hwpwm, duty_cycle, period); + if (err) + return err; -static void gb_pwm_disable(struct pwm_chip *chip, struct pwm_device *pwm) -{ - struct gb_pwm_chip *pwmc = pwm_chip_to_gb_pwm_chip(chip); + /* enable/disable */ + if (!enabled) + return gb_pwm_enable_operation(pwmc, pwm->hwpwm); - gb_pwm_disable_operation(pwmc, pwm->hwpwm); -}; + return 0; +} static const struct pwm_ops gb_pwm_ops = { .request = gb_pwm_request, .free = gb_pwm_free, - .config = gb_pwm_config, - .set_polarity = gb_pwm_set_polarity, - .enable = gb_pwm_enable, - .disable = gb_pwm_disable, + .apply = gb_pwm_apply, .owner = THIS_MODULE, }; -- 2.25.1

[PATCH v2] staging: greybus: audio: fix loop cursor use after iteration

by Jared Kangas

gbaudio_dapm_free_controls() iterates over widgets using the list_for_each_entry*() family of macros from <linux/list.h>, which leaves the loop cursor pointing to a meaningless structure if it completes a traversal of the list. The cursor was set to NULL at the end of the loop body, but would be overwritten by the final loop cursor update. Because of this behavior, the widget could be non-null after the loop even if the widget wasn't found, and the cleanup logic would treat the pointer as a valid widget to free. To fix this, introduce a temporary variable to act as the loop cursor and copy it to a variable that can be accessed after the loop finishes. Due to not removing any list elements, use list_for_each_entry() instead of list_for_each_entry_safe() in the revised loop. This was detected with the help of Coccinelle.

[PATCH] [v2] Kbuild: move to -std=gnu11

by Arnd Bergmann

From: Arnd Bergmann <arnd(a)arndb.de> During a patch discussion, Linus brought up the option of changing the C standard version from gnu89 to gnu99, which allows using variable declaration inside of a for() loop. While the C99, C11 and later standards introduce many other features, most of these are already available in gnu89 as GNU extensions as well. An earlier attempt to do this when gcc-5 started defaulting to -std=gnu11 failed because at the time that caused warnings about designated initializers with older compilers. Now that gcc-5.1 is the minimum compiler version used for building kernels, that is no longer a concern. Similarly, the behavior of 'inline' functions changes between gnu89 and gnu11, but this was taken care of by defining 'inline' to include __attribute__((gnu_inline)) in order to allow building with clang a while ago. One minor issue that remains is an added gcc warning for shifts of negative integers when building with -Werror, which happens with the 'make W=1' option, as well as for three drivers in the kernel that always enable -Werror, but it was only observed with the i915 driver so far. To be on the safe side, add -Wno-shift-negative-value to any -Wextra in a Makefile. Nathan Chancellor reported an additional -Wdeclaration-after-statement warning that appears in a system header on arm, this still needs a workaround. The differences between gnu99, gnu11, gnu1x and gnu17 are fairly minimal and mainly impact warnings at the -Wpedantic level that the kernel never enables. Between these, gnu11 is the newest version that is supported by all supported compiler versions, though it is only the default on gcc-5, while all other supported versions of gcc or clang default to gnu1x/gnu17.
