While going for UART clock off\nUART clock off has multiple state machines and before going into last\nstate it makes sure that there are no pending data in UART Tx and Rx FIFO.\nAlthough there would be one Rx command queued which is flushed before\nmoving to last state and going ahead with UART clock off. If UART clock is\nturned off before Rx flush request is being executed and ADM tried to flush\nRx command, ADM encounters data bus error on UART Rx Channel. Hence with\nwaiting for Rx flush completion, and then doing UART clock off on receving\nthe same would resolve ADM data bus error issue on UART Rx channel.\n\nCRs-Fixed: 457769\nChange-Id: I9344277224a2dc3f28140a1f42aa3feed5411b97\nSigned-off-by: Mayank Rana \u003cmrana@codeaurora.org\u003e\n" }, { "commit": "e833acaf2b5cfac0fb53692652a8c39667f1e559", "tree": "f530c2ea75a3d7e52045e1f543ced58757895b9d", "parents": [ "7dfc4b284ca395a035e7da058f86dfb4275dd509" ], "author": { "name": "Duy Truong", "email": "dtruong@codeaurora.org", "time": "Tue Feb 12 13:35:08 2013 -0800" }, "committer": { "name": "Duy Truong", "email": "dtruong@codeaurora.org", "time": "Tue Feb 12 13:35:08 2013 -0800" }, "message": "Update copyright to The Linux Foundation\n\nChange-Id: Ibead64ce2e901dede2ddd1b86088b88f2350ce92\nSigned-off-by: Duy Truong \u003cdtruong@codeaurora.org\u003e\n" }, { "commit": "46d114077acd537d63cb4c301889e166b947b333", "tree": "98966441f9b46dc36980481f894576969c648013", "parents": [ "3b344f4617be1b61835b319587c50342727deb0d" ], "author": { "name": "Mayank Rana", "email": "mrana@codeaurora.org", "time": "Tue Jan 08 10:15:56 2013 +0530" }, "committer": { "name": "Linux Build Service Account", "email": "lnxbuild@localhost", "time": "Wed Feb 06 13:05:22 2013 -0700" }, "message": "msm_serial_hs: consider flush buffer request only when DMA is in progress\n\nTTY Core uses flush_buffer to clear out any output data before closing\nport, whereas UART application can always request to do flush output data\nbefore starting data transfer using tty supported ioctl().\nreceive_tty_flush is used to make decision on completion of any DMA Tx\ndata transfer.

Probe() is called once only and remove is not called until UARTDM\nplatform device is removed. With this current implementation, although\nexternal device (ex. Bluetooth SoC) is not operational mode, used UARTDM\nGPIOs are configured in active mode which is causing more leakage current\nand more power consumption.\n\nHence configure those UARTDM GPIOs in active mode only when used UARTDM\ndevice is opened and under used.
