* ARM: pxa: irq: fix handling of ICMR registers in suspend/resumeDaniel Mack2018-08-241-2/+2
| | | | | | | | | | | | | | | | | [ Upstream commit 0c1049dcb4ceec640d8bd797335bcbebdcab44d2 ] PXA3xx platforms have 56 interrupts that are stored in two ICMR registers. The code in pxa_irq_suspend() and pxa_irq_resume() however does a simple division by 32 which only leads to one register being saved at suspend and restored at resume time. The NAND interrupt setting, for instance, is lost. Fix this by using DIV_ROUND_UP() instead.

* ARM: pxa: pxa_cplds: fix interrupt handlingRobert Jarzmik2016-10-311-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 9ba63e3cc849cdaf3b675c47cc51fe35419e5117 upstream. Since its initial commit, the driver is buggy for multiple interrupts handling. The translation from the former lubbock.c file was not complete, and might stall all interrupt handling when multiple interrupts occur. This is especially true when inside the interrupt handler and if a new interrupt comes and is not handled, leaving the output line still held, and not creating a transition as the GPIO block behind would expect to trigger another cplds_irq_handler() call. For the record, the hardware is working as follows. The interrupt mechanism relies on : - one status register - one mask register Let's suppose the input irq lines are called : - i_sa1111 - i_lan91x - i_mmc_cd Let's suppose the status register for each irq line is called : - status_sa1111 - status_lan91x - status_mmc_cd Let's suppose the interrupt mask for each irq line is called : - irqen_sa1111 - irqen_lan91x - irqen_mmc_cd Let's suppose the output irq line, connected to GPIO0 is called : - o_gpio0 The behavior is as follows : - o_gpio0 = not((status_sa1111 & irqen_sa1111) | (status_lan91x & irqen_lan91x) | (status_mmc_cd & irqen_mmc_cd)) => this is a N-to-1 NOR gate and multiple AND gates - irqen_* is exactly as programmed by a write to the FPGA - status_* behavior is governed by a bi-stable D flip-flop => on next FPGA clock : - if i_xxx is high, status_xxx becomes 1 - if i_xxx is low, status_xxx remains as it is - if software sets status_xxx to 0, the D flip-flop is reset => status_xxx becomes 0 => on next FPGA clock cycle, if i_xxx is high, status_xxx becomes 1 again Fixes: fc9e38c0f4d3 ("ARM: pxa: lubbock: use new pxa_cplds driver") Reported-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* net: smc91x: fix SMC accessesRussell King2016-09-302-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 2fb04fdf30192ff1e2b5834e9b7745889ea8bbcb ] Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM machines") broke some ARM platforms through several mistakes. Firstly, the access size must correspond to the following rule: (a) at least one of 16-bit or 8-bit access size must be supported (b) 32-bit accesses are optional, and may be enabled in addition to the above. Secondly, it provides no emulation of 16-bit accesses, instead blindly making 16-bit accesses even when the platform specifies that only 8-bit is supported. Reorganise smc91x.h so we can make use of the existing 16-bit access emulation already provided - if 16-bit accesses are supported, use 16-bit accesses directly, otherwise if 8-bit accesses are supported, use the provided 16-bit access emulation. If neither, BUG(). This exactly reflects the driver behaviour prior to the commit being fixed. Since the conversion incorrectly cut down the available access sizes on several platforms, we also need to go through every platform and fix up the overly-restrictive access size: Arnd assumed that if a platform can perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access size needed to be specified - not so, all available access sizes must be specified. This likely fixes some performance regressions in doing this: if a platform does not support 8-bit accesses, 8-bit accesses have been emulated by performing a 16-bit read-modify-write access. Tested on the Intel Assabet/Neponset platform, which supports only 8-bit accesses, which was broken by the original commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch renames GPIOs, which are used to control the power lines to the LCD screen. New names correspond to a real functionality, which was measured on the HTC Magician board_id 0x3a.
