clk: sandbox: Adjust clk-mux.c to emulate reading divider value from HW 2019-07-19T12:50:30+00:00 Lukasz Majewski lukma@denx.de 2019-06-24T13:50:49+00:00 5da0095e3a670fe61a3421a2a826514a61a687e0 The generic mux clock code for CCF requires reading the clock multiplexer value from HW registers. As sandbox by design has readl() as no-op it was necessary to provide this value in the other way. The new field in the mux structure (accessible only when sandbox is run) has been introduced for this purpose. Signed-off-by: Lukasz Majewski <lukma@denx.de>

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12) 2019-07-19T12:50:30+00:00 Lukasz Majewski lukma@denx.de 2019-06-24T13:50:45+00:00 1d7993d1d0efb7727de29ebbe164059b7bf71983 This patch brings the files from Linux kernel (linux-stable/linux-5.1.y SHA1: 5752b50477da)to provide clocks support as it is used on the Linux kernel with Common Clock Framework [CCF] setup. The directory structure has been preserved. The ported code only supports reading information from PLL, MUX, Divider, etc and enabling/disabling the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree. One needs to pay attention to the comments indicating necessary for U-Boot's driver model changes. If needed, the code can be extended to support the "set" part of the clock management.
