add single-wire serial bus interface (SSBI) driver
SSBI is the Qualcomm single-wire serial bus interface used to connect the MSM devices to the PMIC and other devices. Since SSBI only supports a single slave, the driver gets the name of the slave device passed in from the board file through the master device's platform data. SSBI registers pretty early (postcore), so that the PMIC can come up before the board init. This is useful if the board init requires the use of gpios that are connected through the PMIC. Based on a patch by Dima Zavin <dima@android.com> that can be found at: http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=eb060bac4 This patch adds PMIC Arbiter support for the MSM8660. The PMIC Arbiter is a hardware wrapper around the SSBI 2.0 controller that is designed to overcome concurrency issues and security limitations. A controller_type field is added to the platform data to specify the type of the SSBI controller (1.0, 2.0, or PMIC Arbiter). [davidb@codeaurora.org: I've moved this driver into drivers/ssbi/ and added an include for linux/module.h so that it will compile] Signed-off-by: Kenneth Heitke <kheitke@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
