Subject: dt-bindings: timer: renesas,rz-mtu3: Remove TCIU8 interrupt
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6afd8c292d678091d3ba873295cddc1d0502f476;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: timer: renesas,rz-mtu3: Remove TCIU8 interrupt

The TCIU8 interrupt used to be documented in earlier revisions of the
user manuals, but has since been removed. The corresponding entry is now
marked as reserved in the interrupt mapping tables of all supported
SoCs.

 * Page 486, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/G2UL
   Rev.1.40 User Manual
 * Page 363, Table 8.2 Interrupt Mapping (6/13) in the Renesas RZ/Five
   Rev.1.30 User Manual
 * Page 528, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/G2L
   and RZ/G2LC Rev.1.50 User Manual
 * Page 540, Table 8.2 Interrupt mapping (7/13) in the Renesas RZ/V2L
   Rev.1.50 User Manual

Remove the TCIU8 interrupt.
