clk: qcom: gdsc: Ensure regulator init state matches GDSC state

2021-08-26T12:35:13+00:00

[ Upstream commit 9711759a87a041705148161b937ec847048d882e ] 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.

[ Upstream commit 7f54bf2640e877c8a9b4cc7e2b29f82e3ca1a284 ] Caught this when looking at alpha-pll code. Untested but it is clear that this was intended to write to PLL_CAL_L_VAL and not PLL_ALPHA_VAL.
