The patch titled Subject: hexagon: clean up timer-regs.h has been removed from the -mm tree. Its filename was hexagon-clean-up-timer-regsh.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------ From: Nathan Chancellor nathan@kernel.org Subject: hexagon: clean up timer-regs.h

When building allmodconfig, there is a warning about TIMER_ENABLE being redefined:

drivers/clocksource/timer-oxnas-rps.c:39:9: error: 'TIMER_ENABLE' macro redefined [-Werror,-Wmacro-redefined] #define TIMER_ENABLE BIT(7) ^ ./arch/hexagon/include/asm/timer-regs.h:13:9: note: previous definition is here #define TIMER_ENABLE 0 ^ 1 error generated.

The values in this header are only used in one file each, if they are used at all. Remove the header and sink all of the constants into their respective files.

TCX0_CLK_RATE is only used in arch/hexagon/include/asm/timex.h

TIMER_ENABLE, RTOS_TIMER_INT, RTOS_TIMER_REGS_ADDR are only used in arch/hexagon/kernel/time.c.

SLEEP_CLK_RATE and TIMER_CLR_ON_MATCH have both been unused since the file's introduction in commit 71e4a47f32f4 ("Hexagon: Add time and timer functions").

TIMER_ENABLE is redefined as BIT(0) so the shift is moved into the definition, rather than its use.
