Hi Mark, I don't see below patches that I see as applied in latest linux-next. Can you please confirm if they are applied? Applied "spi: tegra114: fix PIO transfer" to the spi tree Applied "spi: expand mode support" to the spi tree Thanks Sowjanya > The patch > spi: tegra114: fix PIO transfer > has been applied to the spi tree at > https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.1 > All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. > You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. > If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. > Please add any relevant lists and maintainers to the CCs when replying to this mail. > > Thanks, > Mark > > From 3f6e3f7843a6a1667ed890ca51a1388fc7bf3429 Mon Sep 17 00:00:00 2001 > From: Sowjanya Komatineni <skomatineni@nvidia.com> > Date: Mon, 15 Apr 2019 14:30:26 -0700 > Subject: [PATCH] spi: tegra114: fix PIO transfer > > This patch fixes PIO mode transfer to use PIO bit in SPI_COMMAND1 register. > Current driver uses DMA_EN instead of PIO bit. > > Signed-off-by: Sowjanya Komatineni <skomatineni@nvidia.com> > Signed-off-by: Mark Brown <broonie@kernel.org> > --- > drivers/spi/spi-tegra114.c | 5 +++-- > 1 file changed, 3 insertions(+), 2 deletions(-) > > diff --git a/drivers/spi/spi-tegra114.c b/drivers/spi/spi-tegra114.c index b57f10182fae..21e4fdad013f 100644 > --- a/drivers/spi/spi-tegra114.c > +++ b/drivers/spi/spi-tegra114.c > @@ -641,8 +641,9 @@ static int tegra_spi_start_cpu_based_transfer( > > tspi->is_curr_dma_xfer = false; > > - val |= SPI_DMA_EN; > - tegra_spi_writel(tspi, val, SPI_DMA_CTL); > + val = tspi->command1_reg; > + val |= SPI_PIO; > + tegra_spi_writel(tspi, val, SPI_COMMAND1); > return 0; > } > > -- > 2.20.1

This patch fixes PIO mode transfer to use PIO bit in SPI_COMMAND1 register. Current driver uses DMA_EN instead of PIO bit. Signed-off-by: Sowjanya Komatineni <skomatineni@nvidia.com> --- drivers/spi/spi-tegra114.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
