The patch titled pxa2xx_spi: restore DRCMR on resume has been removed from the -mm tree. Its filename was pxa2xx_spi-restore-drcmr-on-resume.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: pxa2xx_spi: restore DRCMR on resume From: Daniel Ribeiro <drwyrm@xxxxxxxxx> If DMA is enabled, any spi_sync call after suspend/resume would block forever, because DRCMR is lost on suspend. This patch restores DRCMR to the same values set by probe.
