| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The condition passed to read*_poll_timeout() is the break condition, i.e. wait for this condition to happen and return success. The original code assumed the opposite, resulting in a warning when the PLL clock rate was changed but never lost it's lock as far as the readout indicated. This was verified by checking the read out register value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't have code to handle any of the noc clocks in rk3399 and they're all just listed as critical clocks. Let's do the same for aclk_emmc_noc. Without this clock being marked as critical we have problems around suspend/resume after commit 20c389e656a8 ("clk: rockchip: fix incorrect aclk_emmc source gate bits on rk3399"). Before that change we were presumably not actually gating any of these clocks because we were setting the wrong gate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra114 has a HW bug that the PLLD/PLLD2 lock bit cannot be asserted when the DIS power domain is during up-powergating process but the clamp to this domain is not removed yet. That causes a timeout and aborts the power sequence, although the PLLD/PLLD2 has already locked. To remove the false alarm, we don't use the lock for PLLD/PLLD2. Just wait 1ms and treat the clocks as locked.

So, we should have ".sdsrc" as an internal core clock. Otherwise, since the sdhi driver will calculate clock for a sd card using the wrong parent clock rate, and then performance will be not good.

Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since this code is already not using module_init, case, the init ordering remains unchanged with this commit.

Also all current boards provide an Ethernet reference clock for the PHY externally, hence configuring the internal PHY reference clock. Furthermore, and the actual driver of this patch, specify ethernet related parents at that early point in boot leads to a warning: bad: scheduling from the idle thread! The reason for the warning is that setting the parent enables the ENET PLL since we are using CLK_OPS_PARENT_ENABLE. Enabling the ENET PLL can cause clk_pllv3_wait_lock to sleep. See also: commit fc8726a2c021 ("clk: core: support clocks which requires parents enable (part 2)"). Note that setting the ENET AXI root clock parent also requires ENET PLL to be enabled. However, U-Boot typically leaves the ENET PLL on, hence when the framework sets the parent of the first clock, it does not need to wait for the PLL to come up. But because there is currently no user of that clock, the PLL gets disabled after setting the parent. Therefore, subsequent reparenting calls of any clock which somehow rely on the ENET PLL, need to reenable the ENET PLL which leads to a sleep. Removing those subsequent reparenting calls works around this issue. Also remove comments. The code is really verbose enough.
