global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14Z

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

power: pmic: Add driver for ST-Ericsson AB8500 via PRCMU

2021-07-14T20:48:14Z

All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500 (Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540 although in practice only AB8500 and AB8505 are relevant since the platforms with AB9540 and AB8540 were cancelled and never used in production. In general, the AB8500 PMIC uses I2C as control interface, where the different register banks are represented as separate I2C devices. However, in practice AB8500 is always connected to a special I2C bus on the DB8500 SoC that is controlled by the power/reset/clock management unit (PRCMU) firmware. Add a simple driver that allows reading/writing registers of the AB8500 PMIC. The driver directly accesses registers from the PRCMU parent device (represented by syscon in U-Boot). Abstracting it further (e.g. with the i2c uclass) would not provide any advantage because the PRCMU I2C bus is always just connected to AB8500 and vice-versa. The ab8500.h header is mostly taken as-is from Linux (with some minor adjustments) to allow using similar code in both Linux and U-Boot.

cmd: ti: pd: Add debug command for K3 power domains

2021-06-11T11:04:52Z

Add support command for debugging K3 power domains. This is useful with the HSM rearch setup, where power domains are directly controlled by SPL instead of going through the TI SCI layer. The debugging support is only available in the u-boot codebase though, so the raw register access power domain layer must be enabled on u-boot side for this to work. By default, u-boot side uses the TI SCI layer, and R5 SPL only uses the direct access methods. Signed-off-by: Tero Kristo Signed-off-by: Tero Kristo Reviewed-by: Jaehoon Chung

power: domain: Introduce driver for raw TI K3 PDs

2021-06-11T11:04:52Z

Normally, power domains are handled via TI-SCI in K3 SoCs. However, SPL is not going to have access to sysfw resources, so it must control them directly. Add driver for supporting this. Signed-off-by: Tero Kristo Signed-off-by: Tero Kristo Reviewed-by: Jaehoon Chung

treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30Z

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.
