[PATCH] rtc-pcf8563: detect polarity of century bit automatically The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

drivers/rtc/rtc-pcf8563.c: fix uninitialized use warning gcc-4.9 found a potential condition under which the 'pending' variable may be used uninitialized: drivers/rtc/rtc-pcf8563.c: In function 'pcf8563_irq': drivers/rtc/rtc-pcf8563.c:173:5: warning: 'pending' may be used uninitialized in this function [-Wmaybe-uninitialized] This is because in the pcf8563_get_alarm_mode() function, we check any nonzero return of pcf8563_read_block_data, but in the irq function we only check for negative values, so a possible positive value does not get detected if the compiler chooses not to inline the entire call chain. Checking for any non-zero value in the interrupt handler as well is just as correct and lets the compiler know what we are doing, without needing a bogus initialization.

drivers/rtc/rtc-pcf8563.c: fix pcf8563_irq() error return value As pointed out by Sergei Shtylyov, the pcf8563_irq function contains a bug in the error handling: an interrupt handler is not supposed to return an errno value but an 'enum irqreturn'. Let's fix this by returning IRQ_NONE in case of a communication error.

[PATCH] rtc-pcf8563: detect polarity of century bit automatically The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

[PATCH] rtc-pcf8563: detect polarity of century bit automatically The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

rtc: philips: Make sure clk_init_data is fully initialized The clk_init_data structure contains several mutually-exclusive members for different methods to specify the possible parents of a clock, prompting drivers to initialize only the members they need. However, not initializing all members may cause subtle issues, which are only exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is enabled. Make sure all members are fully initialized, to avoid such bugs, and to prevent future breakage when converting drivers to a different method for specifying the parents.

rtc: pcf8563: fix clock provider leak on unbind pcf8563_clkout_register_clk() registers the CLKOUT clock provider with of_clk_add_provider(), but nothing ever unwinds it: there is no of_clk_del_provider() call and the driver has no remove callback. Each of_clk_add_provider() allocates a struct of_clk_provider, takes a reference on the OF node and adds an entry to the global of_clk_providers list, none of which is released when the device is unbound. Every bind/unbind (or module reload) therefore leaks a provider structure and an of_node reference. The clock itself is already device-managed (devm_clk_register()); only the provider registration was not. Use devm_of_clk_add_hw_provider() so the provider is removed automatically on unbind. Tie it to the parent i2c device, whose OF node carries the #clock-cells and clock-output-names properties (the RTC class device has no OF node of its own).

rtc: use simple i2c probe All these drivers have an i2c probe function which doesn't use the "struct i2c_device_id *id" parameter, so they can trivially be converted to the "probe_new" style of probe with a single argument.

[PATCH] rtc-pcf8563: detect polarity of century bit automatically The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

rtc: rework rtc_register_device() resource management rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

i2c: Convert most new-style drivers to use module aliasing Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

rtc: Use named initializers for arrays of i2c_device_data While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace and commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

Drivers: rtc: remove __dev* attributes. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

rtc: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.
