2021-08-05clk: qcom: gdsc: Ensure regulator init state matches GDSC stateBjorn Andersson
As GDSCs are registered and found to be already enabled gdsc_init() ensures that 1) the kernel state matches the hardware state, and 2) votable GDSCs are properly enabled from this master as well. But as the (optional) supply regulator is enabled deep into gdsc_toggle_logic(), which is only executed for votable GDSCs, the kernel's state of the regulator might not match the hardware. The regulator might be automatically turned off if no other users are present or the next call to gdsc_disable() would cause an unbalanced regulator_disable(). Given that the votable case deals with an already enabled GDSC, most of gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just clearing the SW_COLLAPSE_MASK and enabling hardware control to simply call regulator_enable() in both cases. The enablement of hardware control seems to be an independent property from the GDSC being enabled, so this is moved outside that conditional segment. Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to happen regardless of the initial state this is grouped together with the other sc->pd updates at the end of the function.

The earlycon depends on the bootloader setup UART clocks being retained. There're actually two uart clocks (ipg, per) on MX6QDL, but the 'Fixes' commit change to register only one which means another clock may be disabled during booting phase and result in the earlycon unwork.

2021-08-05clk: divider: Implement and wire up .determine_rate by defaultMartin Blumenstingl
.determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz). Implement .determine_rate in addition to .round_rate so drivers that are using clk_divider_{ro_,}ops can benefit from this by default. Keep the .round_rate callback for now since some drivers rely on clk_divider_ops.round_rate being implemented.

2021-07-29clk: rockchip: make rk3308 ddrphy4x clock criticalYunhao Tian
Currently, no driver support for DDR memory controller (DMC) is present, as a result, no driver is explicitly consuming the ddrphy clock. This means that VPLL1 (parent of ddr clock) will be shutdown if we enable and then disable any child clock of VPLL1 (e.g. SCLK_I2S0_8CH_TX). If VPLL1 is disabled, the whole system will freeze, because the DDR controller will lose its clock. So, it's necessary to prevent VPLL1 from shutting down, by marking the ddrphy4x CLK_IS_CRITICAL. This bug was discovered when I was porting rockchip_i2s_tdm driver to mainline kernel from Rockchip 4.4 kernel. I guess that other Rockchip SoCs without DMC driver may need the same patch. If this applies to other devices, please let us know.

2021-07-29clk: rockchip: drop GRF dependency for rk3328/rk3036 pll typesPeter Geis
The rk3036/rk3328 pll types were converted to checking the lock status via the internal register in january 2020, so don't need the grf reference since then. But it was forgotten to remove grf check when deciding between the pll rate ops (read-only vs. read-write), so a clock driver without the needed grf reference might've been put into the read-only mode just because the grf reference was missing. This affected the rk356x that needs to reclock certain plls at boot. Fix this by removing the check for the grf for selecting the utilized operations.

2021-07-27clk: mediatek: Add configurable enable control to mtk_pll_dataChun-Jie Chen
In all MediaTek PLL design, bit0 of CON0 register is always the enable bit. However, there's a special case of usbpll on MT8192. The enable bit of usbpll is moved to bit2 of other register. Add configurable en_reg and pll_en_bit for enable control or default 0 where pll data are static variables. Hence, CON0_BASE_EN could also be removed. And there might have another special case on other chips, the enable bit is still on CON0 register but not at bit0.

2021-07-27clk: mediatek: Fix asymmetrical PLL enable and disable controlChun-Jie Chen
In fact, the en_mask is a combination of divider enable mask and pll enable bit(bit0). Before this patch, we enabled both divider mask and bit0 in prepare(), but only cleared the bit0 in unprepare(). In the future, we hope en_mask will only be used as divider enable mask. The enable register(CON0) will be set in 2 steps: first is divider mask, and then bit0 during prepare(), and vice versa. But considering backward compatibility, at this stage we allow en_mask to be a combination or a pure divider enable mask. And then we will make en_mask a pure divider enable mask in another following patch series.
