2019-09-01rtc: pcf85363/pcf85263: fix regmap error in set_timeBiwen Li1-1/+6
Issue: - # hwclock -w hwclock: RTC_SET_TIME: Invalid argument Why: - Relative commit: 8b9f9d4dc511 ("regmap: verify if register is writeable before writing operations"), this patch will always check for unwritable registers, it will compare reg with max_register in regmap_writeable. - The pcf85363/pcf85263 has the capability of address wrapping which means if you access an address outside the allowed range (0x00-0x2f) hardware actually wraps the access to a lower address. The rtc-pcf85363 driver will use this feature to configure the time and execute 2 actions in the same i2c write operation (stopping the clock and configure the time). However the driver has also configured the `regmap maxregister` protection mechanism that will block accessing addresses outside valid range (0x00-0x2f). How: - Split of writing regs to two parts, first part writes control registers about stop_enable and resets, second part writes RTC time and date registers.

This result in a selectable range of 1-255 seconds, which covers most embedded Linux use-cases. Clock sources of 4096Hz, 64Hz and 1/60Hz is mostly useful in MCU use-cases.

2019-08-23rtc: pcf2127: bugfix: read rtc disables watchdogBruno Thomsen1-20/+12
The previous fix listed bulk read of registers as root cause of accendential disabling of watchdog, since the watchdog counter register (WD_VAL) was zeroed. Fixes: 3769a375ab83 rtc: pcf2127: bulk read only date and time registers. Tested with the same PCF2127 chip as Sean reveled root cause of WD_VAL register value zeroing was caused by reading CTRL2 register which is one of the watchdog feature control registers. So the solution is to not read the first two control registers (CTRL1 and CTRL2) in pcf2127_rtc_read_time as they are not needed anyway. Size of local buf variable is kept to allow easy usage of register defines to improve readability of code. Debug trace line was updated after CTRL1 and CTRL2 are no longer read from the chip. Also replaced magic numbers in buf access with register defines.

2019-08-23rtc: pcf2127: cleanup register and bit definesBruno Thomsen1-26/+33
Cleanup of defines to follow kernel coding style and increase code readability by using same register and bit define style. Change PCF2127_REG_RAM_{addr_MSB,wrt_cmd,rd_cmd} to upper case as kernel coding guide section 12 'Macros, Enums and RTL' states "Names of macros defining constants and labels in enums are capitalized". Improve readability of RAM register comment by making whole sentences. Remove parentheses from register defines as they are only used for expressions and not constants. As there are no clear style for name of registers and bits in the kernel drivers, I suggest the following for at least this driver, but hopefully also other RTC drivers. Register name should follow this convention: [chip]_REG_[reg name] 0xXX Bit name should follow this convention, so it clearly states which chip register it's part of: [chip]_BIT_[reg name]_[bit name] BIT(X) Additionally I suggest bit defines are always placed right below its corresponding register define and using an extra tab indentation for the BIT(X) part. This will visually make it easy to see that bit defines are part of the complete register definition. Rename PCF2127_OSF to PCF2127_BIT_SC_OSF and move it right below PCF2127_REG_SC. This will improve readability of bit checks as it's easy to verify that it uses the correct register. Move end of line comments above register defines as it's more like a heading for 1 register define and up to 8 bit defines or a collection of registers that are close related like timestamp split across 6 registers.

2019-08-23rtc: sun6i: Add support for H6 RTCOndrej Jirman1-2/+38
RTC on H6 is mostly the same as on H5 and H3. It has slight differences mostly in features that are not yet supported by this driver. Some differences are already stated in the comments in existing code. One other difference is that H6 has extra bit in LOSC_CTRL_REG, called EXT_LOSC_EN to enable/disable external low speed crystal oscillator. It also has bit EXT_LOSC_STA in LOSC_AUTO_SWT_STA_REG, to check whether external low speed oscillator is working correctly. This patch adds support for enabling LOSC when necessary: - during reparenting - when probing the clock H6 also has capacbility to automatically reparent RTC clock from external crystal oscillator, to internal RC oscillator, if external oscillator fails. This is enabled by default. Disable it during probe.
