* clk: imx8m: fix clock tree update of TF-A managed clocksAhmad Fatoum2021-09-181-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit d36207b848a6490e14664e2197a1c8ab51d8148e ] On the i.MX8M*, the TF-A exposes a SiP (Silicon Provider) service for DDR frequency scaling. The imx8m-ddrc-devfreq driver calls the SiP and then does clk_set_parent on the DDR muxes to synchronize the clock tree. Since 936c383673b9 ("clk: imx: fix composite peripheral flags"), these TF-A managed muxes have SET_PARENT_GATE set, which results in imx8m-ddrc-devfreq's clk_set_parent after SiP failing with -EBUSY: echo 25000000 > userspace/set_freq imx8m-ddrc-devfreq 3d400000.memory-controller: failed to set dram_apb parent: -16 Fix this by adding a new i.MX composite flag for firmware managed clocks, which clears SET_PARENT_GATE. This is safe to do, because updating the Linux clock tree to reflect reality will always be glitch-free.

* clk: imx: Fix reparenting of UARTs not associated with stdoutAdam Ford2021-05-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 379c9a24cc239000b1dec53db02fe17a86947423 ] Most if not all i.MX SoC's call a function which enables all UARTS. This is a problem for users who need to re-parent the clock source, because any attempt to change the parent results in an busy error due to the fact that the clocks have been enabled already. clk: failed to reparent uart1 to sys_pll1_80m: -16 Instead of pre-initializing all UARTS, scan the device tree to see which UART clocks are associated to stdout, and only enable those UART clocks if it's needed early. This will move initialization of the remaining clocks until after the parenting of the clocks. When the clocks are shutdown, this mechanism will also disable any clocks that were pre-initialized.

* clk: imx8m: fix bus critical clk registrationPeng Fan2020-11-041-0/+5
| | | | | | | | | | | | | | | | | | | | noc/axi/ahb are bus clk, not peripheral clk. Since peripheral clk has a limitation that for peripheral clock slice, IP clock slices must be stopped to change the clock source. However if the bus clk is marked as critical clk peripheral, the assigned clock parent operation will fail. So we added CLK_SET_PARENT_GATE flag to avoid glitch. And add imx8m_clk_hw_composite_bus_critical for bus critical clock usage Fixes: 936c383673b9e ("clk: imx: fix composite peripheral flags") Reviewed-by: Abel Vesa <abel.vesa@nxp.com> Reported-by: Abel Vesa <abel.vesa@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com> Link: https://lore.kernel.org/r/1604229834-25594-1-git-send-email-peng.fan@nxp.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>

The end goal is to get rid of all these macros when there will be no more users of the clk based API, that is, when all the i.MX clock provider drivers will be switched completely to the clk_hw based API. This is another step in moving away from the non clk_hw based API usage throughout the i.MX clock drivers. The reason for doing that is to have a clear split between the clock provider and the clock consumer API.

| | | | | | | | | | | | | | | | | DRAM frequency switches are executed in firmware and can change the configuration of the DRAM PLL outside linux. Mark these CLKs with CLK_GET_RATE_NOCACHE so we always read back the PLL config registers and recalculate rates. In current DRAM frequency tables on 8mm/8mn only the maximum frequency uses the PLL so it's always configured in the same way. However reading back the PLL configuration is the correct behavior and allows additional setpoints in the future.
