| * clk: shmobile: div6: Make clock-output-names optionalGeert Uytterhoeven2015-12-081-10/+3
| | | | | | | | | | | | | | | | | | | | | | | | Renesas DIV6 clocks provide a single clock output. Hence make the "clock-output-names" DT property optional instead of mandatory. In case the DT property is omitted the DT node name will be used. Rename the variable "name" to "clk_name" to make the code more similar with fixed-factor-clock.c, and to avoid a conflict with a nested local variable while we're at it.

| | | | | | | | | | | | | | | | | | | | | | | | | | Shmobile is all multiplatform these days, so get rid of the reference to CONFIG_ARCH_SHMOBILE_MULTI in drivers/clk/shmobile/. Also instead of always enabling DIV6 and MSTP adjust the Makefile to enable DIV6 and MSTP depending on if they are included in the SoC or not.

| * clk: shmobile: mstp: Consider "zb_clk" suitable for power managementGeert Uytterhoeven2015-09-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the CPG/MSTP Clock Domain code looks for MSTP clocks to power manage a device. Unfortunately, on R-Mobile APE6 (r8a73a4) and SH-Mobile AG5 (sh73a0), the Bus State Controller (BSC) is not power-managed by an MSTP clock, but by a plain CPG clock (zb_clk). Add a special case to handle this, so the clock is properly managed, and devices connected to the BSC work as expected.

| * clk: shmobile: div6: Avoid changing divisor in .disable()Geert Uytterhoeven2015-01-081-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While DIV6 clocks require the divisor field to be non-zero when stopping the clock, some clocks (e.g. ZB on sh73a0) fail to be re-enabled later if the divisor field is changed when stopping the clock. The reason for this is unknown. To fix this, do not touch the divisor field if it's already non-zero. On kzm9g, the smsc911x Ethernet controller is connected to the sh73a0 Bus State Controller, which is clocked by the ZB clock. Without this fix, if the ZB clock is disabled during system suspend, and re-enabled during resume, the kernel locks up when the smsc911x driver tries to access the Ethernet registers.

Mostly fixes and enhancements to existing drivers as well as new drivers. This tag contains a bit more arch code than I usually take due to some OMAP2+ changes. Additionally it contains the restart notifier handlers which are merged as a dependency into several trees. The PXA changes are the only messy part. Due to having a stable tree I had to revert one patch and follow up with one more fix near the tip of this tag. Some dead code is introduced but it will soon become live code after 3.18-rc1 is released as the rest of the PXA family is converted over to the common clock framework. Another trend in this tag is that multiple vendors have started to push the complexity of changing their CPU frequency into the clock driver, whereas this used to be done in CPUfreq drivers. Changes to the clk core include a generic gpio-clock type and a clk_set_phase() function added to the top-level clk.h api. Due to some confusion on the fbdev mailing list the kernel boot parameters documentation was updated to further explain the clk_ignore_unused parameter, which is often required by users of the simplefb driver. Finally some fixes to the locking around the clock debugfs stuff was done to prevent deadlocks when interacting with other subsystems." * tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux: (99 commits) clk: pxa clocks build system fix Revert "arm: pxa: Transition pxa27x to clk framework" clk: samsung: register restart handlers for s3c2412 and s3c2443 clk: rockchip: add restart handler clk: rockchip: rk3288: i2s_frac adds flag to set parent's rate doc/kernel-parameters.txt: clarify clk_ignore_unused arm: pxa: Transition pxa27x to clk framework dts: add devicetree bindings for pxa27x clocks clk: add pxa27x clock drivers arm: pxa: add clock pll selection bits clk: dts: document pxa clock binding clk: add pxa clocks infrastructure clk: gpio-gate: Ensure gpiod_ APIs are prototyped clk: ti: dra7-atl-clock: Mark the device as pm_runtime_irq_safe clk: ti: LLVMLinux: Move __init outside of type definition clk: ti: consider the fact that of_clk_get() might return an error clk: ti: dra7-atl-clock: fix a memory leak clk: ti: change clock init to use generic of_clk_init clk: hix5hd2: add I2C clocks clk: hix5hd2: add watchdog0 clocks ...

| | | | | | | | | | | | | | | | | | | | | | If the driver needs to change a clock rate, then it must be propogated through the MSTP clock to the parent clock (such as shdi0 -> sd0).
