Tero Kristo authored
The introduction of support for CLK_SET_RATE_PARENT flag for clkctrl clocks used a generic clock flag, which causes a conflict with the rest of the clkctrl flags, namely the NO_IDLEST flag. This can cause boot failures on certain platforms where this flag is introduced, by omitting the wait for the clockctrl module to be fully enabled before proceeding with rest of the code. Fix this by moving all the clkctrl specific flags to their own bit-range. Signed-off-by:

The AB8540 was an evolved version of the AB8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the AB8500.

Since hclk_sd and pclk_ddr source clock from CPLL or GPLL, and these two PLL may change their frequency. If we do not assign right id to pclk_ddr and hclk_sd, they will alway use default cur register value, and may get the frequency exceed their signed off frequency. So assign correct Id for them, then we can assign frequency for them in dts. Signed-off-by:

The newly added clock notifier may return an error code but so far the error output in the function would only return an error pointer from registering the clock. So when the clock notifier fails the clock would be unregistered but the return would still be the clock pointer which could then not be dereferenced correctly. So fix the error handling to prevent that. Fixes: 60cf09e4 ("clk: rockchip: Restore the clock phase after the rate was changed") Signed-off-by:

commit c420c1e4db22 ("clk: rockchip: Prevent calculating mmc phase if clock rate is zero") catches one gremlin again for clk-rk3228.c that the parent of SDMMC phase clock should be sclk_sdmmc0, but not sclk_sdmmc. However, the naming of the sdmmc clocks varies in the manual with the card clock having the 0 while the hclk is named without appended 0. So standardize one one format to prevent confusion, as there also is only one (non-sdio) mmc controller on the soc. Signed-off-by:

This adds a new driver for the USB PHY clocks in the CFGCHIP2 syscon register on TI DA8XX-type SoCs. The USB0 (USB 2.0) PHY clock is an interesting case because it calls clk_enable() in a reentrant way. The USB 2.0 PSC only has to be enabled temporarily while we are locking the PLL, which takes place during the clk_enable() callback. Signed-off-by:
