rtc: hym8563: fix a missing check of block data read

2019-01-22T18:03:43+00:00

When i2c_smbus_read_i2c_block_data() fails, the read data in "buf" could be incorrect and should not be used. The fix checks if i2c_smbus_read_i2c_block_data fails, and if so, return its error code upstream. Signed-off-by: Kangjie Lu Signed-off-by: Alexandre Belloni

rtc: hym8563: in .read_alarm set .tm_sec to 0 to signal minute accuracy

2016-07-19T16:18:06+00:00

Set .tm_sec to 0 instead of -1 to signal minute accuracy. Signed-off-by: Uwe Kleine-König Signed-off-by: Alexandre Belloni

rtc: simplify implementations of read_alarm

2016-07-09T08:24:45+00:00

Since commit d68778b80dd7 ("rtc: initialize output parameter for read alarm to "uninitialized"") there is no need to explicitly set unsupported members to -1. So drop the respective assignments from drivers. Signed-off-by: Uwe Kleine-König Signed-off-by: Alexandre Belloni

rtc: hym8563: Remove CLK_IS_ROOT

2016-05-20T10:33:51+00:00

This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate CLK_IS_ROOT", 2016-02-02) so remove it. Cc: Heiko Stuebner Signed-off-by: Stephen Boyd Signed-off-by: Alexandre Belloni

rtc: hym8563: fix invalid year calculation

2016-03-14T16:08:38+00:00

Year field must be in BCD format, according to hym8563 datasheet. Due to the bug year 2016 became 2010. Fixes: dcaf03849352 ("rtc: add hym8563 rtc-driver") Signed-off-by: Alexander Kochetkov Signed-off-by: Alexandre Belloni

rtc: Drop owner assignment from i2c_driver

2015-09-05T11:19:06+00:00

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Alexandre Belloni

rtc: hym8563: make the irq optional

2015-06-24T23:13:45+00:00

Sometimes the irq line is not connected to any soc-pin. This does not hinder basic timekeeping functionality of the rtc, so probe should not fail in this case. Signed-off-by: Heiko Stuebner Signed-off-by: Alexandre Belloni

drivers/rtc/rtc-hym8563.c: fix swapped enable/disable of clockout control bit

2015-04-17T13:04:02+00:00

The hym8563 datasheet describes the clock output control-bit as "when set to logic 0, the square wave output is enable, when set to logic 1, the CLKOUT output is inhibited". But in reality the setting is exactly opposite. Before now, the clock output was not really used, but on the rk3288 soc this generated clock is used to supply the temperature sensor block and the swapped bit value prevented it from working. With the corrected value, the tsadc now reports correct values.

drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled

2015-04-17T13:04:01+00:00

When the clock is disabled, do not return a rate of 0 but instead return the rate the clock will be running at after it gets enabled. This prevents problems when the core clock code is trying to determine a suitable rate, while the clock is still off.
