| * clk: rpi: add Raspberry Pi 4 supportAhmad Fatoum2022-06-171-11/+31
| | | | | | | | | | | | | | | | | | | | | | | | Our Raspberry Pi clock driver is a hack, but it works well enough for older Rpis and just needs one more clock to support the SD-Card on the Raspberry Pi 4, so add that. In return, we remove bcm2835-cs, which we won't use on Raspberry Pi 4, because we'll leverage the ARM architected timer instead.

* clk: handle NULL args in clk_set_parent()Bastian Krause2022-05-121-1/+6
| | | | | | | | | | | | | | | | | | | | NULL struct clk pointers should be treated just as the Linux kernel clk driver does [1]. The reasoning should also apply to the parent clk argument. A NULL struct clk pointer can happen for example on the Freescale i.MX6 SABRE Smart Device Board if CONFIG_DRIVER_VIDEO_IMX_IPUV3 is disabled, leading to assigned-clocks IMX6QDL_CLK_LDB_DI0_SEL and IMX6QDL_CLK_LDB_DI1_SEL [2] being unavailable. Without this patch, the board hangs while setting those assigned clock configurations since [3].

| | | | | | | | | | | | | | | | | | Commit f6ce1103fdc4 ("ARM: rpi: move clk support to a separate driver") replaced board code setting up clocks with clkdev_add_physbase() with a proper cprman driver that registers fixed clocks and can be referenced from device tree. It was not fully equivalent though, because the mini UART's clock was no longer registered as that is provided by a different clock controller. Import the Linux v5.17 bcm2835-aux-clk driver to fix console usage on Raspberry Pi 3b.

| | | | | | | | | | | We didn't have the need to handle %pOF specially yet, but for the error message in clk-bulk, not readily knowing what component couldn't get its clocks is annoying. Print the node name directly and change the error code to the error string if those are compiled in.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An assigned-clock-parents referring to a fixed-clock will result in a warning: WARNING: clk: couldn't get parent clock 0 for /ethernet@fe300000 That's because the device for the fixed clock is created on demand and even after ensuring probe, no driver will have bound against it as CLK_OF_DECLARE operates outside the driver model. Fix this by creating devices and binding the dummy driver while iterating over the CLK_OF_DECLARE list. No functional change for systems not enabling deep-probe.

* / include: add dedicated header for printf/printkAhmad Fatoum2021-11-013-3/+3
|/ | | | | | | | | | | | Including <stdio.h> for printf is a bit problematic, because it pulls in other headers for <console.h>, which includes quite a few more headers as well. To make it easier to share code between barebox and host tools make <printk.h> the new minimal header for printf and move the extra logging stuff into <linux/printk.h>.
