Pull more ARM multiplatform updates from Arnd Bergmann: "The second part of the multiplatform changes now converts the Intel/Marvell PXA platform along with the rest. The patches went through several rebases before the merge window as bugs were found, so they remained separate. This has to touch a lot of drivers, in particular the touchscreen, pcmcia, sound and clk bits, to detach the driver files from the platform and board specific header files" * tag 'arm-multiplatform-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (48 commits) ARM: pxa/mmp: remove traces of plat-pxa ARM: pxa: convert to multiplatform ARM: pxa/sa1100: move I/O space to PCI_IOBASE ARM: pxa: remove support for MTD_XIP ARM: pxa: move mach/*.h to mach-pxa/ ARM: PXA: fix multi-cpu build of xsc3 ARM: pxa: move plat-pxa to drivers/soc/ ARM: mmp: rename pxa_register_device ARM: mmp: remove tavorevb board support ARM: pxa: remove unused mach/bitfield.h ARM: pxa: move clk register definitions to driver ARM: pxa: move smemc register access from clk to platform cpufreq: pxa3: move clk register access to clk driver ARM: pxa: remove get_clk_frequency_khz() ARM: pxa: pcmcia: move smemc configuration back to arch ASoC: pxa: i2s: use normal MMIO accessors ASoC: pxa: ac97: use normal MMIO accessors ASoC: pxa: use pdev resource for FIFO regs Input: wm97xx - get rid of irq_enable method in wm97xx_mach_ops Input: wm97xx - switch to using threaded IRQ ...

rtc: rzn1: Fix a variable type

2022-05-24T23:24:21Z

The calculation in ->set_offset() handles both negative and positive offsets. The 'steps' variable will be checked to be in a specific [-x; +x] range, which means it must be a signed integer rather than unsigned. This also fixes the following smatch warning: warn: 'steps' 'true' implies 'steps > 0' is 'true' Fixes: be4a11cf98af ("rtc: rzn1: Add oscillator offset support") Reported-by: Dan Carpenter Signed-off-by: Miquel Raynal Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20220520082500.489248-1-miquel.raynal@bootlin.com

rtc: rzn1: Avoid mixing variables

2022-05-24T23:19:12Z

In the ->set_offset() callback, the 'val' variable is used for two different purposes at the same time, which is oviously wrong: - It contains the intermediate value of the SUBU register that must be written at the end of ->set_offset(). - It is used in the middle of the above calculations to poll the CTL2 register for a specific value. Let's introduce a 'ctl2' variable just for the readl_poll_timeout() call and use it there in place of 'var'. In order to avoid mixing those two variables again, let's rename the remaining occurences of 'val' into 'subu' and initialize it to 0 to avoid the uninitialized variable situation reported by Tom Rix and Colin Ian King already.

2022-05-19T10:08:17Z

In the error handling path, the clk_prepare_enable() function call should be balanced by a corresponding 'clk_disable_unprepare()' call , as already done in the remove function. clk_disable_unprepare calls clk_disable() and clk_unprepare(). They will use IS_ERR_OR_NULL to check the argument.
