2019-02-06Input: gpio-keys - add shutdown callbackFlorian Fainelli1-0/+10
On some platforms (e.g.: ARCH_BRCMSTB) it is possible to enter "poweroff" while leaving some wake-up sources enabled such as key presses in order to allow for the system to wake-up. Wire up a .shutdown() callback which calls into the existing gpio_keys_suspend() since the logic is essentially the same.

2019-02-04Input: sx8654 - do not override interrupt triggerDmitry Torokhov1-1/+1
We should rely on the interrupt trigger (level vs edge) set up by the firmware or board code instead of forcing what we consider appropriate. Signed-off-by: Dmitry Torokhov <[email protected]>
2019-02-04Input: sx8654 - convert #defined flags to BIT(x)Richard Leitner1-5/+6
Some of the #defined register values are one-bit flags. Convert them to use the BIT(x) macro instead of 1 byte hexadecimal values. This improves readability and clarifies the intent. Signed-off-by: Richard Leitner <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk fixes from Stephen Boyd: "Mostly driver fixes, but there's a core framework fix in here too: - Revert the commits that introduce clk management for the SP clk on MMP2 SoCs (used for OLPC). Turns out it wasn't a good idea and there isn't any need to manage this clk, it just causes more headaches. - A performance regression that went unnoticed for many years where we would traverse the entire clk tree looking for a clk by name when we already have the pointer to said clk that we're looking for - A parent linkage fix for the qcom SDM845 clk driver - An i.MX clk driver rate miscalculation fix where order of operations were messed up - One error handling fix from the static checkers" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: qcom: gcc: Use active only source for CPUSS clocks clk: ti: Fix error handling in ti_clk_parse_divider_data() clk: imx: Fix fractional clock set rate computation clk: Remove global clk traversal on fetch parent index Revert "dt-bindings: marvell,mmp2: Add clock id for the SP clock" Revert "clk: mmp2: add SP clock" Revert "Input: olpc_apsp - enable the SP clock"
