regmap: fix regmap_read_poll_timeout warning about sandbox_timer_add_offset

2019-04-23T09:17:15Z

When fixing sandbox test for regmap_read_poll_timeout(), the sandbox_timer_add_offset was introduced but only defined in sandbox code thus generating warnings when used out of sandbox : include/regmap.h:289:2: note: in expansion of macro 'regmap_read_poll_timeout_test' regmap_read_poll_timeout_test(map, addr, val, cond, sleep_us, \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/spi/meson_spifc.c:169:8: note: in expansion of macro 'regmap_read_poll_timeout' ret = regmap_read_poll_timeout(spifc->regmap, REG_SLAVE, data, ^~~~~~~~~~~~~~~~~~~~~~~~ drivers/spi/meson_spifc.c: In function 'meson_spifc_txrx': include/regmap.h:277:4: warning: implicit declaration of function 'sandbox_timer_add_offset' [-Wimplicit-function-declaration] This fix adds a timer_test_add_offset() only defined in sandbox, and renames the previous sandbox_timer_add_offset() to it.

test: dm: regmap: Fix the long test delay

2019-01-15T00:47:13Z

At present one of the regmap tests takes 5 seconds to run since it waits for a timeout. This should be handled using sandbox_timer_add_offset() which advances time for test purposes. This requires a little change to make the regmap_read_poll_timeout() testable. Update the macro and the test.

regmap: Add endianness support

2018-11-14T17:16:27Z

Add support for switching the endianness of regmap accesses via the "little-endian", "big-endian", and "native-endian" boolean properties in the device tree. The default endianness is native endianness. Signed-off-by: Mario Six Reviewed-by: Simon Glass Reviewed-by: Daniel Schwierzeck

regmap: Define regmap_{get,set}

2018-11-14T17:16:27Z

It would be convenient if one could use the regmap API in conjunction with register maps defined as structs (i.e. structs that directly mirror the memory layout of the registers in question). A similar approach was planned with the regmap_write32/regmap_read32 macros, but was never used. Hence, implement regmap_set/regmap_range_set and regmap_get/regmap_range_get macros, which, given a register map, a struct describing the layout of the register map, and a member name automatically produce regmap_read/regmap_write calls that access the specified member in the register map.

regmap: Support reading from specific range

2018-11-14T17:16:27Z

It is useful to be able to treat the different ranges of a regmap separately to be able to use distinct offset for them, but this is currently not implemented in the regmap API. To preserve backwards compatibility, add regmap_read_range and regmap_write_range functions that take an additional parameter 'range_num' that identifies the range to operate on.

regmap: Add raw read/write functions

2018-11-14T17:16:27Z

The regmap functions currently assume that all register map accesses have a data width of 32 bits, but there are maps that have different widths. To rectify this, implement the regmap_raw_read and regmap_raw_write functions from the Linux kernel API that specify the width of a desired read or write operation on a regmap. Implement the regmap_read and regmap_write functions using these raw functions in a backwards-compatible manner. Reviewed-by: Anatolij Gustschin Signed-off-by: Mario Six Reviewed-by: Simon Glass
