The original binding doc is writing in the format of:
Required properties:
-- compatible : Should be "fsl,<chip>-esdhc"
It just provides a rule and does not provide the specific compatible string.
So i did not update the doc before.
But i think it's better to fix it to avoid future warning again.
Can you help add below patch before this commit or do you need me
to resend the patch series again with this patch added?

Subject: [PATCH 6/8] mmc: sdhci-esdhc-imx: using specific compatible string
in binding doc
Using specific compatible string in binding doc to make the binding
more clear.
It's also used to avoid checkpatch warning in the future like follows:
0005-mmc-sdhci-do-not-enable-card-cd-wakeup-for-gpio-case.patch has no obvious style problems and is ready for submission.
WARNING: DT compatible string "fsl,imx6sx-usdhc" appears un-documented -- check ./Documentation/devicetree/bindings/
+ { .compatible = "fsl,imx6sx-usdhc", .data = &usdhc_imx6sx_data, },
total: 0 errors, 1 warnings, 18 lines checked
