| | | | | | | | | | | | | | | | | | | | | | | | | | This ports over a couple of changes that accrued upstream between v5.6, when we last synchronized, and v5.8-rc1: 5bf7f4a24938 clk: at91: sam9x60: Don't use audio PLL b0ecf1c6c6e8 clk: at91: usb: continue if clk_hw_round_rate() return zero 43b203d32b77 clk: at91: sam9x60: fix usb clock parents d7a83d67a169 clk: at91: usb: use proper usbs_mask 9962fb0d1995 clk: at91: usb: introduce num_parents in driver's structure 12dc8d3be9d8 clk: at91: add at91sam9g45 pmc driver 0969b242f7b8 clk: at91: add sama5d3 pmc driver 143e04dab6b4 clk: at91: add at91sam9n12 pmc driver 02ff48e4d7f7 clk: at91: add at91rm9200 pmc driver 99e107439eea clk: at91: Add peripheral clock for PTC f6363c437dc6 clk: at91: pmc: do not continue if compatible not located 7425f246f725 clk: at91: optimize pmc data allocation 99767cd4406f clk: at91: allow setting PCKx parent via DT 03a1ee1dad0e clk: at91: allow setting all PMC clock parents via DT Besides fixes, mostly around sam9x60, this adds support for the new a91 device tree clock bindings that were extended to the sama5d3 in v5.8-rc1.

Reword it, but leave the option as-is as some boards may be broken if we drop the option (e.g. because they still depend on a probe order or call default_environment_path_set, but don't explicitly detect the device).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The enet_out clock gate is wrongly abstracted. The bit it is controlling is not just a bit to enable the clock, it also controls the direction of the ethernet reference clock. When the bit is cleared, the ethernet reference clock must be fed into the SoC from an external oscillator; when it's set then the ethernet reference clock is generated internally. The correct setting depends on the board, so we must not set the bit unconditionally during probe of the clock driver. Whether or not the clock is enabled can be selected by the board by removing the clock from the FEC in its dts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Port over the at91bootstrap driver to barebox. Some parts are based on the U-Boot and Linux implementations. To support future use in PBL, the driver model and driver implementation parts are split into separate files with the latter being compilable for PBL as well. Registers, which are found in the common Linux sdhci.h have been added to the barebox sdhci.h. Registers which appear to be Atmel specific have been added to atmel-sdhci-common.c instead. The driver still misses some parts, which will follow later: - ADMA is unsupported, PIO only for now - Only the SD/MMC controller already enabled by the first stage bootloader is supported. Further clocking changes appear to be necessary to enable another Both can be retrofitted later on and don't hold us back from booting from MMC.
