| | | | | | | | | | The commit also introduces the HAVE_FB_IMX config that is to be selected from the MX25 platform config. Once this commit gets merged, the two other i.MX archs, ARCH_MX1 and ARCH_MX2, should follow this one.

* imx-serial-excessive-status-clearing-on-break.patchAndy Green2010-02-16
| | | | | | | | | | | | | | | | | | | | | | | cc: Sasha Hauer <kernel@pengutronix.de> We noticed that we were only able to communicate once with a GSM module per session, if we powered down the module then the serial driver was broken until reset, no traffic or /proc/interrupts activity could be seen any more. Volker noticed it was provoked by a long "break" seen on the wire when the RX was not driven during powerdown, we discovered we could kill the serial driver just by forcing RX low extenally for a little while. I saw that the processing for BREAK in the driver gets too excited and clears down all set bits in USR2, including that a character is pending. This stops all further characters getting processed. The attached one-liner makes the serial driver immortal against BREAK.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old names are defined only if the cpp symbol IMX_NEEDS_DEPRECATED_SYMBOLS exists, which is defined (for now) for all files below arch/arm/mach-mx1. This was done earlier for mx2 and mx3, too. USBD_INT0 is for now defined unconditionally to prevent breaking drivers/usb/gadget/imx_udc. While at it use IMX_IO_ADDRESS to define MX1_IO_ADDRESS which adds a cast to the IO_ADDRESS macro fixing many warnings like arch/arm/mach-mx1/generic.c:51: warning: passing argument 1 of 'mxc_init_irq' makes pointer from integer without a cast .
