They have been added with a status disabled in order to keep our legacy unchanged. It is actually not enough to keep our legacy unchanged. First, just a reminder about our use case: TF-A (BL2) loads and starts OP-TEE, then loads and runs U-Boot. U-Boot code checks if an OP-TEE is running, if yes it searches in Kernel device tree if an OP-TEE node is present: -If the OP-TEE node is not present then U-Boot copies OP-TEE node and its reserved memory region from U-Boot device tree to the kernel device tree. -If the OP-TEE node is present then it does nothing (this OP-TEE node will be used by Linux). So U-Boot lets the kernel device tree unchanged thinking it is correct for an OP-TEE usage. It is the case for our legacy boards, the OP-TEE node is present (although disabled) but the reserved memory region is not declared. As no memory region has been reserved for OP-TEE, the end of DDR is seen by the kernel as free and then used for CMA. But as OP-TEE is running, this end of DDR is already used by OP-TEE. So as soon as kernel tries to access to the CMA region OP-TEE raises an error. To fix it, all OP-TEE node and SCMI is moved in a dedicated file.

Measurements have shown that after enabling the LDO the voltage on VDDPU_CAP jumps to ~750mV in the first step and after that the regulator executes the normal ramp up as defined by the step size control. This means it takes the regulator between 360us and 370us to ramp up to the nominal 1.15V voltage for this power domain. With the old setting of the ramp delay the power up of the PU GPC domain would happen in the middle of the regulator ramp with the voltage being at around 900mV. Apparently this was enough for most units to properly power up the peripherals in the domain and execute the reset. Some units however, fail to power up properly, especially when the chip is at a low temperature. In that case any access to the GPU registers would yield an incorrect result with no way to recover from this situation. Change the ramp delay to 380us to cover the measured ramp up time with a bit of additional slack.

Internals of that implementation are not visible outside OMAP1 directory. As a consequence, device drivers are not able to register clocks potentially provided by peripheral devices. Drop OMAP1 implementation of the clock API and enable common clock framework. Modify the remaining low level code to be compatible with clock provider API and register the clocks with CCF. Move initialisation of clocks to omap1_timer_init() to avoid memory allocation issues at early setup phase from where omap1_init_early() is called. Register the clocks after initialization of clock I/O registers, local clock pointers used by OMAP1 clock ops, and local .rate fields of clocks with no local implementation of .recalc ops, so CCF structures are populated with correct data during clock registration. Instead of enabling some of the registered clocks, flag them for CCF as critical. Introduce .is_enabled op using code that verifies hardware status of clock enablement, split out from implementation of .disable_unused op, so the latter is actually called by CCF for not requested but hardware enabled clocks. Add .round_rate ops where missing so .set_rate ops are called by CCF as expected. Since CCF allows parallel execution of .enable/.disable and .set_rate ops, protect registers shared among those groups of ops from concurrent access with spinlocks. Drop local debugfs support in favor of that provided by CCF. v2: flag tc2_ck as CLK_IS_CRITICAL (Aaro) v3: rebase on top of soc/omap1-multiplatform-5.18, - drop no longer needed includes from arch/arm/mach-omap1/io.c Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
