Linux for the Switch

* Stop unconditionally polling for RC_STATUS_PHY_RDY at the entry of the threaded IRQ handler. Once IRQ_RX_PKT_RCVD is received we can read immediately the packet from the buffer. However we still need to wait afterwards for RC_STATUS_PHY_RDY, to make sure that the ACK (in case requested) was processed and send out by the Radio Controller, before we issue the next CMD_RC_RX. This significantly reduces the overall time spend in the threaded IRQ handler. * Avoid raise condition between xmit and coincident packet reception, by disabling the IRQ and clearing the IRQ status upon xmit entry. * Introduce helper functions adf7242_clear_irqstat() and adf7242_cmd_rx() Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Stefan Schmidt <stefan@osg.samsung.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
