Robin Gong March 10, 2020, 11:31 a.m. UTC 
ERR009165 fixed on i.mx6ul/6ull/6sll. All other i.mx6/7 and
i.mx8m/8mm still need this errata. Please refer to nxp official
errata document from https://www.nxp.com/ .

For removing workaround on those chips. Add new i.mx6ul type.

Erm, no. A i.MX51 ECSPI is a i.MX51 ECSPI and not a i.MX6UL ECSPI. If
you want to handle them equally somewhere then explicitly test for
i.MX6ul *and* i.MX51 there.

Changed again, but the PIO case still not honoured. This should look
like
	if (spi_imx->usedma && spi_imx->devtype_data->tx_glitch_fixed)
		ctrl |= MX51_ECSPI_CTRL_SMC;
	else
		ctrl &= ~MX51_ECSPI_CTRL_SMC;

That explains the variable introduced in the last patch, ok.

I have the impression that splitting up 06/13 and 07/13 into two patches
doesn't make it easier to review.

But all i.mx6 chips including i.MX53 ECSPI are almost same as i.MX51 ECSPI, and ERR00915 is fixed from i.mx6ul....

But 06 is a errata for all i.mx6 legacy chips, while 07 is for i.mx6ul and newer chips which have been already fixed the HW issue. I think two patches are better.

You introduce .devtype = IMX6UL_ECSPI in this series, so apparently it
is *not* the same as IMX51_ECSPI, then please also don't introduce a
function which claims they are the same.

Okay, I'll add is_imx6ul_ecspi explicitly.
