From mboxrd@z Thu Jan 1 00:00:00 1970 From: cyrille.pitchen@atmel.com (Cyrille Pitchen) Date: Tue, 9 Dec 2014 14:31:31 +0100 Subject: [PATCH 0/5] tty/serial: at91: fix atmel_serial_probe(), dma_sync_* and the Hardware Handshaking support Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This series of patches fix many bugs: - a wrong enum type was used when calling dma_sync_*_for_cpu() and dma_sync_*_for_device() - IO accesses to registers were done in atmel_serial_probe() after the peripheral clock had been disabled. - the -EDEFER error was not handled properly in atmel_serial_probe() - the Hardware Handshaking mode could never be enabled to control the RTS line The patches were made from the next-20141205 tag of the linux-next repository. They were tested on a SAMA5Dx FPGA platform.
