clk: mmp: pxa1908: Instantiate power driver through auxiliary bus

2025-09-21T17:48:44+00:00

The power domain driver shares the APMU clock controller's registers. Instantiate the power domain driver through the APMU clock driver using the auxiliary bus. Also create a separate Kconfig entry for the PXA1908 clock driver to allow (de)selecting the driver at will and selecting CONFIG_AUXILIARY_BUS.

clk: mmp: frac: convert from round_rate() to determine_rate()

2025-09-08T13:41:27+00:00

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series. Signed-off-by: Brian Masney

clk: mmp2: call pm_genpd_init() only after genpd.name is set

2025-01-08T19:13:48+00:00

Setting the genpd's struct device's name with dev_set_name() is happening within pm_genpd_init(). If it remains NULL, things can blow up later, such as when crafting the devfs hierarchy for the power domain: Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read ... Call trace: strlen from start_creating+0x90/0x138 start_creating from debugfs_create_dir+0x20/0x178 debugfs_create_dir from genpd_debug_add.part.0+0x4c/0x144 genpd_debug_add.part.0 from genpd_debug_init+0x74/0x90 genpd_debug_init from do_one_initcall+0x5c/0x244 do_one_initcall from kernel_init_freeable+0x19c/0x1f4 kernel_init_freeable from kernel_init+0x1c/0x12c kernel_init from ret_from_fork+0x14/0x28 Bisecting tracks this crash back to commit 899f44531fe6 ("pmdomain: core: Add GENPD_FLAG_DEV_NAME_FW flag"), which exchanges use of genpd->name with dev_name(&genpd->dev) in genpd_debug_add.part().
