Subject: [PATCH 0/2] Add software flow control support for STM32 UART
Date: Sun, 12 Apr 2020 23:39:21 +0530	[thread overview]
Message-ID: <20200412180923.30774-1-mani@kernel.org> (raw)

From: Manivannan Sadhasivam <mani@kernel.org>

Hello,

This patchset adds software flow control support for STM32 UART controller.
This is necessary for the upcoming STM32MP1 based board called Stinger96
IoT-Box. On that board, a bluetooth chip is connected to one of the UART
controller but the CTS/RTS lines got swapped mistakenly. So in order to
workaround that hardware bug and also to support the usecase of using only
Tx/Rx pins, this patchset adds software flow control support.

This patchset has been validated w/ Stinger96 IoT-Box connected to Murata
WiFi-BT combo chip.

Thanks,
Mani
