2020-07-09rtc: i2c_rtc_emul: catch any write to the "reset" registerRasmus Villemoes
It's more natural that any write that happens to touch the reset register should cause a reset, rather than just a write that starts at that offset. Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de> Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>
2020-07-09rtc: sandbox-rtc: fix set methodRasmus Villemoes
The current set method is broken; a simple test case is to first set the date to something in April, then change the date to 31st May: => date 040412122020.34 Date: 2020-04-04 (Saturday) Time: 12:12:34 => date 053112122020.34 Date: 2020-05-01 (Friday) Time: 12:12:34 or via the amending of the existing rtc_set_get test case similarly: $ ./u-boot -T -v => ut dm rtc_set_get Test: dm_test_rtc_set_get: rtc.c expected: 31/08/2004 18:18:00 actual: 01/08/2004 18:18:00 The problem is that after each register write, sandbox_i2c_rtc_complete_write() gets called and sets the internal time from the current set of registers. However, when we get to writing 31 to mday, the registers are in an inconsistent state (mon is still 4), so the mktime machinery ends up translating April 31st to May 1st. Upon the next register write, the registers are populated by sandbox_i2c_rtc_prepare_read(), so the 31 we just wrote to mday gets overwritten by a 1. Fix it by writing all registers at once, and for consistency, update the get method to retrieve them all with one "i2c transfer".

2020-07-09rtc: fall back to ->{read, write} if ->{read, write}8 are not providedRasmus Villemoes
Similar to how the dm_rtc_{read,write} functions fall back to using the {read,write}8 methods, do the opposite in the rtc_{read,write}8 functions. This way, each driver only needs to provide either ->read8 or ->read to make both rtc_read8() and dm_rtc_read() work - without this, a driver that provides ->read() would most likely just duplicate the logic here for implementing a ->read8() method in term of its ->read() method. The same remarks of course apply to the write case. Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de> Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>
2020-07-09rtc: add dm_rtc_write() helperRasmus Villemoes

Some users may want to read multiple consecutive 8-bit registers. Instead of each caller having to implement the loop, provide a dm_rtc_read() helper. Also, allow a driver to provide a ->read method, which can be more efficient than reading one register at a time.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-07-09rtc: pcf2127: Fixed bug with rtc settings and getting error timeChuanhua Han
The previous pcf2127 RTC chip could not read and set the correct time. When reading the data of internal registers, the read address was the value of register plus 1. This is because this chip requires the host to send a stop signal after setting the register address and before reading the register data. This patch sets the register address using dm_i2c_write and reads the register data using the original dm_i2c_xfer in order to generate a stop signal after the register address is set, and fixes the bug of the original read and write time.
