The PCI part of the DesignWare I2C driver does a lot of things that are not required anymore. For example drivers aren't supposed to handle PCI state transitions themselves. This is all provided by the PCI bus core already. In addition to that there is no point scheduling RPM suspend on driver's idle hook but instead we can use RPM autosuspend for this (which is enabled in the driver already). As a bonus, this patch also fixes following compile warning which is emitted when the driver was compiled without CONFIG_PM_RUNTIME set: drivers/i2c/busses/i2c-designware-pcidrv.c:245:12: warning: ‘i2c_dw_pci_runtime_idle’ defined but not used [-Wunused-function] Reported-by: Nxinhui.pan <xinhuix.pan@intel.com> Reported-by: NJingoo Han <jg1.han@samsung.com> Signed-off-by: NMika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: NWolfram Sang <wsa@the-dreams.de>

This patch allows to set independantly SCL and SDA falling times. The tLOW period is computed by taking into account the SCL falling time. The tHIGH period is computed by taking into account the SDA falling time. For instance in case the margin on tLOW is considered too small, it can be increased by increasing the SCL falling time which is by default set at 300ns. The same applies for tHIGH period with the help of SDA falling time.

Class based instantiation can cause noticeable delays when booting. This mechanism is used when it is not possible to describe slaves on I2C busses. As we do have other mechanisms, most embedded I2C will not need classes and for embedded it is explicitly not recommended to use them. Add a deprecation warning for drivers which want to disable class based instantiation in the near future to gain boot-up time, so users relying on this technique can switch to something better. They really should. Signed-off-by: NWolfram Sang <wsa@the-dreams.de>

Since the runtime PM state is expected to be active according to the amba bus, we must align our behaviour while probing to it. Moreover, this is needed to be able to have the driver fully functional without depending on CONFIG_RUNTIME_PM. Since the device is active while a successful probe has been completed, the reference counting for the clock will be screwed up and never reach zero. We resolve this by implementing runtime PM callbacks and let them handle the resources accordingly, including the clock.
