git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk fix from Stephen Boyd: "One fix for the composite clk that broke when we changed this clk type to use the determine_rate instead of round_rate clk op by default. This caused lots of problems on Rockchip SoCs because they heavily use the composite clk code to model the clk tree" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: composite: Also consider .determine_rate for rate + mux composites
2021-10-18clk: composite: Also consider .determine_rate for rate + mux compositesMartin Blumenstingl1-5/+5
Commit 69a00fb3d69706 ("clk: divider: Implement and wire up .determine_rate by default") switches clk_divider_ops to implement .determine_rate by default. This breaks composite clocks with multiple parents because clk-composite.c does not use the special handling for mux + divider combinations anymore (that was restricted to rate clocks which only implement .round_rate, but not .determine_rate). Alex reports: This breaks lot of clocks for Rockchip which intensively uses composites, i.e. those clocks will always stay at the initial parent, which in some cases is the XTAL clock and I strongly guess it is the same for other platforms, which use composite clocks having more than one parent (e.g. mediatek, ti ...) Example (RK3399) clk_sdio is set (initialized) with XTAL (24 MHz) as parent in u-boot. It will always stay at this parent, even if the mmc driver sets a rate of 200 MHz (fails, as the nature of things), which should switch it to any of its possible parent PLLs defined in mux_pll_src_cpll_gpll_npll_ppll_upll_24m_p (see clk-rk3399.c) - which never happens. Restore the original behavior by changing the priority of the conditions inside clk-composite.c. Now the special rate + mux case (with rate_ops having a .round_rate - which is still the case for the default clk_divider_ops) is preferred over rate_ops which have .determine_rate defined (and not further considering the mux).

As per RZ/G2L HW(Rev.0.50) manual, clock monitor register value 0 means clock is not supplied and 1 means clock is supplied. This patch fixes the issue by removing the inverted logic. Fixing the above, triggered following 2 issues 1) GIC interrupts don't work if we disable IA55_CLK and DMAC_ACLK. Fixed this issue by adding these clocks as critical clocks. 2) DMA is not working, since the DMA driver is not turning on DMAC_PCLK. So will provide a fix in the DMA driver to turn on DMA_PCLK.
