[PATCH 02/15] staging: wfx: reduce timeout for chip initial start up

From: Jérôme Pouiller The device take a few hundreds of milliseconds to start. However, the current code wait up to 10 second for the chip. We can safely reduce this value to 1 second. Thanks to that change, it is no more necessary to use an interruptible timeout. Signed-off-by: Jérôme Pouiller

[PATCH 07/15] staging: wfx: introduce a way to poll IRQ

From: Jérôme Pouiller It is possible to check if an IRQ is ending by polling the control register. This function must used with care: if an IRQ fires while the host reads control register, the IRQ can be lost. However, it could be useful in some cases. Signed-off-by: Jérôme Pouiller --- driver

[PATCH 08/15] staging: wfx: poll IRQ during init

From: Jérôme Pouiller When the chip starts in SDIO mode, the external IRQ (aka Out-Of-Band IRQ) cannot be used before to configure it. Therefore, the first exchanges with the chip have to be done without the OOB IRQ. This patch allow to poll the data until the OOB IRQ is correctly setup. In orde

From: Jérôme Pouiller When used over SDIO bus, device is able to use an external line to signal IRQs (also called Out-Of-Band IRQ). The current code have several problems: 1. The ISR cannot directly acknowledge IRQ since access to the bus is not atomic. This patch use a threaded IRQ to sol
