clk: renesas: move drivers to renesas directory

2016-03-03T19:22:53+00:00

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

Along with the above mentioned Kconfig changes it seems appropriate
to also rename directories that only hold drivers for such SoCs.

     support on R-Car H3,
   - Add more module clocks for R-Car H3.

clk: shmobile: div6: Fix .recalc_rate() using a stale divisor

2016-02-26T11:03:10+00:00

cpg_div6_clock_set_rate() only programs the new divisor if the clock
isn't stopped. If the clock is stopped, it will update the cached
divisor value only, which will be programmed into the clock registers
when enabling the clock later.

However, cpg_div6_clock_recalc_rate() reads the divisor from the clock
registers instead of using the cached value, leading to an incorrect
result if the clock is currently stopped.

Make cpg_div6_clock_recalc_rate() use the cached value to fix this.

The parent clock hasn't been validated yet.

The parent clock isn't documented in the datasheet, use S2D1 as a best
guess for now.

clk: shmobile: Free 'clock' on error path

2016-02-25T20:25:31+00:00

We forgot to free this clock when we return early in this code.

clk: shmobile: check for failure

2016-02-24T23:01:42+00:00

We were not checking the return from devm_add_action() which can fail.
Start using the helper devm_add_action_or_reset() and return directly
as we know that the cleanup has been done by this helper.
