2021-10-12rtc: ds1307: Handle oscillator-stop bit correctlyMark Tomlinson
The DS1307 driver was originally based on the DS1337 driver. However, the functionality of the clock set/get functions has diverged. In the original DS1337 driver, the set/get functions did the following: 1) Setting the clock ensured the oscillator was enabled. 2) Getting the clock checked and reset the oscillator-stop flag. The DS1307 does not have an oscillator-stop flag, but the driver tried (incorrectly) to emulate this by ensuring the oscillator was running. It really makes no sense to start a stopped clock without setting it. This patch makes the DS1307 driver behave like the original DS1337 driver again. For the DS1307 itself, this is just a removal of code, since there is no oscillator-fail bit to check or reset, and the clock is started when it is set. Since the DS1307 driver can now also be used for the DS1337 and DS1340 which do have this bit, add code to handle the oscillator-stop bit in the same was the original DS1337 driver did -- i.e. report that the oscillator had stopped and clear the flag. This means that setting the date using the date command (which does both a get and a set) will now clear the oscillator-stop flag in addition to setting and starting the clock. The old-style (non-DM) code has not been updated and will be removed in a future patch. Note that this older code does not support the DS1337, as there is a separate driver for this. Also note that the original (DM) code used the wrong control-register address for the DS1337. Signed-off-by: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C deprecation warnings for most 32-bit boards. It also includes some smaller refactorings that pave the way for more changes, mostly driven by needing to support the Allwinner RISC-V SoC later on. Board wise we gain support for the FriendlyARM NanoPi R1S H5 router board and official Pinetab support. Build-tested for all 160 sunxi boards, and boot tested on a A64, A20, H3, H6, and H616 board.

Both previously used i2c_soft; replace this with the i2c-gpio instance that already exists in those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus). Since the i2c-gpio nodes are not referenced by any other node in the device trees (the device trees have no panel node), the I2C bus is selected by its node name. This panel initialization code was the only i2c_soft user, so the i2c_soft GPIO setup code can be removed now as well.

2021-10-12i2c: Add a DM_I2C driver for the sun8i RSB controllerSamuel Holland
This bus controller is used to communicate with an X-Powers AXP PMIC. Currently, various drivers access PMIC registers through a platform- specific non-DM "pmic_bus" interface, which depends on the legacy I2C framework. In order to convert those drivers to use DM_PMIC, this bus needs a DM_I2C driver. Refactor the rsb functions to take the base address as a parameter, and implement both the existing interface (which is still needed in SPL) and the DM_I2C interface on top of them. The register for switching between I2C/P2WI/RSB mode is the same across all PMIC variants, so move that to the common header. There are only a couple of pairs of hardware/runtime addresses used across all PMIC variants. So far the code expected only the "primary" pair, but some PMICs like the AXP305 and AXP805 use the secondary pair, so add support for that to the DM driver as well.

2021-10-11clk: ti: add am33xx/am43xx spread spectrum clock supportDario Binacchi
The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs. As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for DDR, PER, and CORE PLLs. Calculating the required values and setting the registers accordingly was taken from the set_mpu_spreadspectrum routine contained in the arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project. In locked condition, DPLL output clock = CLKINP *[M/N]. In case of SSC enabled, the reference manual explains that there is a restriction of range of M values. Since the clk_ti_am3_dpll_round_rate() attempts to select the minimum possible N, the value of M obtained is not guaranteed to be within the range required. With the new "ti,min-div" parameter it is possible to increase N and consequently M to satisfy the constraint imposed by SSC.

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will remove the asm/arch/gpio.h header. In preparation, clean up the various files that include it. Some files did not contain any GPIO code at all, so this header was completely unused. A few files contained only legacy platform-specific GPIO code for setting up pin muxes. They were left unchanged, as that code will be completely removed by the DM_PINCTRL migration. The remaining files contain some combination of DM_GPIO and legacy GPIO code. For those, switch to including asm/gpio.h (if it wasn't included already). Right now, this header provides both sets of functions, because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the right header to include once the DM_GPIO migration is complete and GPIO_EXTRA_HEADER is no longer needed.
