Core changes:
- None really.
New drivers:
- AMD ISP411 "AMD ISP" driver.
- Exynos 2200 and 7870 SoC subdrivers.
- Sophgo RISC-V SG2042 and SG2044 subdrivers.
- Amlogic A4 subdriver.
- Rockchip RK3528 subdriver.
- Broadcom BCM21664 subdriver.
- Allwinner A523/T527 subdriver.
- Ingenic X1600 subdriver.
- Microchip SAMA7D65 subdriver, essentially a re-branded
Atmel AT91 PIO4 driver, but nowadays a Microschip SoC line.
Improvements:
- Bring in the devm_kmemdup_array() helper and use it throughout,
also bring in changes to other subsystems for this to establish
this helper.
- Support EGPIO on the Qualcomm SA8775P SoC.
- Extend EINT support in the Mediatek driver.

Pinctrl is an essential driver for SpacemiT's SoC,
The uart driver requires it, same as sd card driver,
so let's enable it by default for this SoC.
The CONFIG_PINCTRL_SPACEMIT_K1 isn't enabled when using
'make defconfig' to select kernel configuration options.
This result in a broken uart driver where fail at probe()
stage due to no pins found.

The map pointer is freed by pinctrl_utils_free_map(). It must not be a
devm_ pointer or it leads to a double free when the device is unloaded.
This is similar to a couple bugs Harshit Mogalapalli fixed earlier in
commits 3fd976afe9 ("pinctrl: nuvoton: fix a double free in
ma35_pinctrl_dt_node_to_map_func()") and 4575962aee ("pinctrl: sophgo:
fix double free in cv1800_pctrl_dt_node_to_map()").

SpacemiT's K1 SoC has a pinctrl controller which use single register
to describe all functions, which include bias pull up/down(strong pull),
drive strength, schmitter trigger, slew rate, mux mode.
